The root is most prominantluy represented by PES *ngd ‘to traveľ.
PWS
*ngh - to shine, to dawn (Fronzaroli 1965a: 138, 145; Kogan 2011: 196)
PWS
*ngŝ - to push, to press, to drive to work (CDG 393; Appleyard 1977: 51; Kogan 2015: 457)
Probably related to Akk. nagāšu ‘to leave, to go away’, in which case the transitive meaning “to drive” may be regarded as a common innovation of CS/EthS. Conversely, there is hardly any connection between this root and Mhr. nəgūŝ ‘to shake milk for butter’, Jib. ngɔŝ id.
PWS
*nVḫ- - mucus, phlegm (SED I No. 197; Kogan 2011: 226)

PWS
*namal-/*naml- - ant (SED II No. 163; Kogan 2011: 212)
There is no reliable reflex of this root in Akkadian, as both namlu and lamattu do not give the impression of being autochthonous Akkadian words (see SED II No. 163 for a comprehensive discussion; cf. also Hrůša 2010:255)
